Change the name of your image_file = forms.ImageField() to be image_file_w200_png. What you are doing there currently is defining a new field rather than changing your existing field because the names are not the same.

You could also define it in a different way in your class Meta: section. You can add a dictionary called widgets and write it like this:

Kafka message are sent to single topic instead of n retry topic and dlt

Asked 2021-Oct-05 at 17:05

I am trying to implement n-retry topic with DLT but all the messages are being pushed to a single topic test-topic-retry-0, there are 3 duplicate records in test-topic-retry-0 which are supposed to be like this:

test-topic-retry-0 -> 1 message after failure
test-topic-retry-1 -> 1 message after the first retry
test-topic-dlt -> 1 message after all the retries failed

It seems like Kafka is pushing all the messages to same topic.

QUESTION

Kerberos PKINIT - No matching entry found preauth (pkinit) verify failure: Certificate mismatch

Asked 2021-May-21 at 11:33

I have installed a FreeIPA master server including Kerberos. Furthermore I have one client server, enrolled in FreeIPA, to test the PKINIT feature of Kerberos. All servers run on CentOS7. A testuser exists in FreeIPA and this user is also listed in the one and only existing realm, when using list_principals in kadmin as testuser@REALMNAME.

getprinc testuser also gives Attributes: REQUIRES_PRE_AUTH.

I have created kdc and client certificates strictly following the documentation: https://web.mit.edu/kerberos/www/krb5-latest/doc/admin/pkinit.html. They have been signed by my own CA, whose certificate is also present on the client and the master.

The [realm] config on the master is as follows:
